8.2 Typical Application

Figure 8-1 shows an ultrasonic gas meter front end. The ultrasonic front end design utilizes time of flight (TOF) measurement to determine the amount of gas flowing in a pipe. The circuit utilizes the MSP430FR5994, two ultra low power operational amplifiers, OPA835 and OPA836, along with two TMUX1119, 2:1 precision switches.
